Hey bro,
Excellent post, should raise a lot of questions and bring out some good discussion. I wonder why you mention only girls? Do you think that guys can't be exploited? I'm just stirring the waters here because I work for a content provider, and I have no problem with it at all. If the photos we sold did not have IDs and Model Releases I might have a different opinion, but it is all perfectly consentual. The models have to sign the forms in order to prove that they are doing it all willingly.
As for my personal opinion, well, I've been looking at porn for years. It makes me feel good, it keeps me going when I don't have someone to play around with (which can sometimes be a loooong time, LOL!!!). So in my own way, I am helping the industry that has brought me so much joy.
